Sampling
Study Population
Adult household members living in the areas of the Senegal River Valley in the areas of Delta and Podor.
Deviations from Sample Design
Mathematica:
In the Podor region, IMPAQ was not able to identify its treatment sample since they did not know at the time of baseline data collection which households in the treatment area would be allocated land in the new irrigation perimeter. Consequently, they asked ANSD to survey (1) all 1,617 households enumerated from the census in the treatment area, with the intent that a substantial portion of the surveyed households would eventually be treated, and (2) a random subsample of 585 households in the comparison area to meet sample size requirements from their power calculations.
